Difference Between MD5 and SHA1

Safe & SecurityComputer NetworkAlgorithms

In this post, we will understand the difference between MD5 and SHA1 −

MD5

  • It stands for Message Digest.

  • It can have 128 bits as length of the message digest.

  • Its speed is fast in comparison to SHA1.

  • To understand the initial message, the aggressor would require 2^128 operations.

  • It is simple.

  • It doesn’t provide good security.

  • If the assailant requires to look for 2 messages that have identical message digest, then the assailant would have to perform 2^64 operations.

  • MD5 was presented in 1992.

SHA1

  • It stands for Secure Hash Algorithm.

  • It can have 160 bits as length of the message digest.

  • Its speed is slow in comparison to MD5.

  • To understand the initial message, the aggressor would require 2^160 operations.

  • It is more complex in comparison to MD5.

  • It provides a decent amount of security.

  • The assailant would need to perform 2^80 operations which is greater than MD5.

  • It was presented in 1995.
